Incisal Edge Troughing

Use a micro bur from Brasseler

Teeth after troughing

Place strips of choice interproximaly to protect while etching

Applying Etch

Bonding agent placed

Use the 8A placement instrument to place Renamel Nano universal composite into troughed area

Use Cosmedent Multi-Use instrument to create a slight depression in the Nano composite to allow room for overlay of Microfill composite.

Notice the slight depression

Application of Renamel Microfill

Application of Renamel Microfill

Microfill after 60 second cure

Checking occlusion with articulating paper

Make adjustments with coarse disc not a bur

Follow with medium disc

Fine disc

Superfine disc

Rubber wheel

Use FlexiStrip Course/Medium then Fine/Superfine to polish the interproximal.

Check occlusion once more

Final restoration after use of Enamelize polishing paste applied with FlexiBuff.

INCISAL EDGE TROUGHING

Tooth preparation is shown using Brassler micro-prep burs. Then application of a microhybrid or nanofill composite material is illustrated. The composite material is condensed into the incisal troughed area to simulate dentin and to create strength and opacity. The composite is left slightly under-contoured to allow for the overlay of Renamel Microfill, the enamel layer. The addition of a microfill composite will give your restoration better wear, better polishability, and long term color stability. At this stage make sure to check for proper occlusion. Lastly the restoration is finished and polished using Cosmedent's Mini FlexiDiscs System followed by Enamelize polishing paste. No burs should be utilized at this point.
